Metasurfaces are two-dimensional (2-D) metamaterials that can control scattering waves of a light beam. Their applications include thin-sheet polarizers, beam splitters, beam steerers and lenses. These structures can control ...

A team of researchers at Université Côte d'Azur and Hokkaido University have recently carried out a study exploring the spontaneous formation of spiral patterns observed on the downward-facing free surface of a horizontal ...

Complex, three-dimensional (3-D) structures are regularly constructed using a reliable commercial method of 3-D laser micro- and nanoprinting. In a recent study, Frederik Mayer and co-workers in Germany and Australia have ...

If you've ever walked past a bees nest on a hot summer day, you've probably been too focused on avoiding getting stung, rather than stopping to wonder how all those bees stay cool. Don't worry, Harvard scientists have braved ...

Using European Southern Observatory's Very Large Telescope (VLT), astronomers have investigated the galaxy NGC 1365. The study, presented in a paper published January 18 on the arXiv.org pre-print server, reveals essential ...

Physicists have discovered a new effect, which makes it possible to create excellent thermal insulators which conduct electricity. Such materials can be used to convert waste heat into electrical energy.

Solar flares shouldn't produce X-rays, but they do. Why? The one-size-fits-all approach to electron collisions misses a lucky few that lead to an intense X-ray burst. Scientists thought there were too many electron-scattering ...

NASA's InSight lander has placed its second instrument on the Martian surface. New images confirm that the Heat Flow and Physical Properties Package, or HP3, was successfully deployed on Feb. 12 about 3 feet (1 meter) from ...
